Usage

Command Line Interface

You can use the geo2zip command to find the closest ZIP code for a given latitude and longitude.

geo2zip <latitude> <longitude>

Example:

geo2zip 37.7749 -122.4194

This command will output the closest ZIP code to the provided coordinates.

As a Python Library

You can also use the Geo2Zip class directly in your Python code:

from geo2zip import Geo2Zip

# Initialize with the path to your data file
geo2zip = Geo2Zip('path/to/geo_zip/data/geo_zip.csv')

# Find the closest ZIP code
latitude = 37.7749
longitude = -122.4194
closest_zip = geo2zip.find_closest_zip(latitude, longitude)
print(f"The closest ZIP code to ({latitude}, {longitude}) is {closest_zip}")

Data

The dataset used for ZIP codes and their coordinates is extracted from the 2023 US Gazetteer Files. The CSV file is included in the package at geo2zip/data/geo2zip.csv.

Testing

Simple and stupid Tests are written using pytest. To run the tests, execute the following command:
